The Question:

O.K., experts. Where can I find the best beaches in the United
States?

The Answer:

According to Dr. Stephen P. Leatherman, or "Dr. Beach," the country's
best beaches are in Hawaii. Dr. Beach is a professor of environmental
studies at Florida International University, and the author of
America's Best Beaches. Of the 16 beaches he's
given a top ranking to as of 2006, 11 are in Hawaii.

If you'd rather stay in the contiguous 48 states, try Florida.
It got the other five spots.
